I think we can both agree that it is not clear right now how life on earth was produced. Naturally we are provided with little direct evidence about the pathways taken by life. However, what is possible, and what is occurring today, is that we can elucidate what KIND of reactions and what kind of chemicals would be required in order for life to form in the conditions under which it did. Despite the fact that we can’t just cook up a batch of E. coli in the space of a few hours as some creationists seem to expect, the amount of progress we have made towards understanding abiogenesis is very hard to account for if there is some principle which entails that life cannot come from non-life. From <a href="http://www.talkorigins.org/faqs/faq-abiogenesis.html:" target="_blank">http://www.talkorigins.org/faqs/faq-abiogenesis.html:</a> “Unfortunately, the conditions that lead to the synthesis of sugars would poison the synthesis of purines, and vice versa. Because of this, authors have speculated that the syntheses of the two compounds were separated in space or time. While this may strike you as an ad hoc requirement, there is an excellent chemicalrationale for it: if the early Earth had a neutral, as opposed to reducing, atmosphere (the current best guess) then formaldehyde (and hence sugars) may have readily formed, but cyanide would have been quickly scavenged into other forms unsuitable for purine biosynthesis. However, cyanide (and purines) would likely have entered the prebiotic environment in two other ways: first, from comets, which have been shown to be rich in cyanide(s). A huge amount of organic material, possibly as much as was created by atmospheric chemistry, was delivered to the Earth during the time preceding abiogenesis. It is likely that the kinetic energy of comet entry would have led to the synthesis of a variety of compounds, including purines, from stored cyanide. Second, besides the atmosphere and comets, the other primary center for the synthesis organic compounds was deep sea hydrothermal vents. Here the chemistry was likely much more suitable for the synthesis of purines from cyanide than in the atmosphere. Thus, we have the synthesis of sugars in the atmosphere and upper reaches of the ocean, and the synthesis of purines during the impact of comets and in the lower reaches of the ocean: as hypothesized, separation in space and time. “ By the way, I suggest you take a look at the rest of that URL. It not only Obviously we cannot expect to produce the sheer volume of chemicals reacting on the early earth, let alone keep these reactions going on anywhere near the scale sufficient to produce primitive cellular life. What we can do and what we do, is examine the various components of life and see what kind of processes could have produced them. The fact is, although we have of course not synthesized living systems from scratch, we do know how self-replicating processes can initiate, how membranes can form and how metabolic systems can develop.

I am certainly not begging the question of natural origins, my assumption is that nature exists whether or not God created it. (one which, I daresay, you do not disagree with.) If nature came from God, jolly good, because it appears that God’s nature has blindly produced life, even if the force behind it all did anticipate what was going to happen. As things stand, I am of course not convinced that the universe was designed for life any more than the human hand was designed for finger painting. Quote:

--------------------------------------------------I don’t see how you can say in no sense are these shapes designed. The results require a computer and a program DESIGNED by Conway that incorporates rules and mathematics. ------------------------------------------------ "Designed" is not the point. The relevant issue is "designed for what?". Neither the computer nor Conway's program were designed to produce the more sophisticated objects in Life - from glider guns and glider eaters onwards. IOW, glider guns are not designed - unless you can show that Conway had them in mind when formulating the rules for Life. In a similar sense, Mandelbrot did not design the Mandelbrot set when he decided to investigate the asymptotic properties of the simple complex polynomial f(z)=z^2+c. Regards, HRG. |

Ed, this is bunk. And no matter how often you repeat it, it will remain bunk. Hydrogen and helium from the Big Bang IS sufficient to produce personal beings! We now understand the key stages in sufficient detail to see how it can happen. Therefore your statement that "no form of unguided impersonal process could do so according to the law of sufficient cause" is refuted. What you're saying is equivalent to "factories cannot produce automobiles because factories aren't mounted on wheels". A wheeled vehicle can be produced by a non-wheeled structure, just as an intelligent being can be produced by unguided evolution: to argue otherwise, you must demonstrate that the mechanism isn't up to the task, not simply declare that it's impossible just because the created entity has something that the creating mechanism lacks. Evolution sure looks like a "suficient cause" to me. |

BTW, I've started an interesting companion thread to this one <a href="http://iidb.org/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=50&t=000066" target="_blank">here</a>. Anyone is free to look it over.

An appeal to "The universe just came to be..." and "Logic may not have been in effect before the big bang..." seem like cries of desperation. People who oppose the idea of a First Cause seem to be arguing not on an intellectual level, but an emotional one. To say that xians are completely irrational, and then to throw logic itself out the window in your argument is self-defeating.
As far as who this First Cause is... Could it be Allah or Brahman? I cannot say for sure... I do know that the Bible makes some claims that do jive with the whole BB/First Cause debate though. In the Bible are the claims of a beginning of space and time. That God transcends these dimensions. That God is unchangable, a quality of a being outside of time. And that the universe is undergoing continual expansion. The interesting thing about BB cosmology, is that it demands a non-physical "substance" as the cause of the universe. |
